If you listen on a butt set while a call is hung up, you should be able to hear the disconnect from the telco and see it on your toner. You will see your polarity lite flicker.

Nickels: I did put my butt-set on the telco pairs & listened to the call process take place. I hear CP answer & route the call properly, I’m also able to hear the customer leave the message in the General MB & they hang up. The call continues to stay off hook and the call connection is never dropped. I remain on the line and what appears to be a telco message “your call did not go through, press 0 for the operator, then I receive a worble tone & eventually the call drops. I will check the polarity light

Sounds to me like the Telco is not sending Disconnect. You can try and roll the pair, I have had that fix it before.

Another user suggested I try this as well!!!

If you get the Recording from Telco on your Butt-Set at the D-mark then odds are that Telco is not sending it.
Try this, have someone call in and have someone on the Norstar answer the call.
Put a Voltmeter across the Telco pr (should be something like 6 to 8 volts).
Then have the far end hang up and the person on the Norstar just stay on the line. You should see your voltage drop to 0-1 within 5 seconds then return to around 48 volts.

That is what should happen just make sure the meter is set to DC and not AC.

I'm back on site and it seems as though the Norstar is releasing when I make test calls, but the CP100 won't. I made test calls to an extension I leave a message, I clip onto line one to listen and the call pilot won't drop the call after you leave a message?

The difference in your test is that I assume you are hanging up on a set on the phone system, which in turn disconnects the call. What happens when you get someone to call in and get them to hang up on the other end?

Over and out!

No that's not correct, I am able to connect/disconnect from my cell to an extension.
When I get into the CP after I leave a message the call doesn't drop right away. It takes over a minute and then the call drops. Still onsite banging my head!!!

So do you see the voltage change or if you are using your toner, do you see the disconnect coming from the Telco?
